flag_negative isn't stored in data_t because if it were, I'd have to make a deep copy of every number when I only want to make it negative for a temporary calculation.
Maybe a DSEL could help in this case.
A domain-specific embedded language? I don't know anything about such programming, but from what I've been able to find, it sounds like a heck of a lot of work for very little benefit.
The benefit is performances. DSEL is not simple, but for the user of the library this will be a clear benefit.
flag_fixedlength isn't stored in data_t because that would defeat the purpose of it, which is to identify a fixed_integer to the allocation functions when no data_t has been allocated for it yet.
Maybe this can be stored on fixed interger then?
How? fixed_integer doesn't handle its own allocation, it relies on base_integer to do that.
See the mail form Jeffrey. CRTP should help. best, Vicente
